TECHNICAL FIELD

This invention relates to a composition for treating or preventing glomerulopathy, especially glomerulonephritis and diabetic nephropathy, having a superior antiproteinuric effect and to a novel compound having superior inhibitory activity for type IV collagenase and an antiproteinuric effect and a composition containing it for treating or preventing.

BACKGROUND ART

A glomerulus is organized by epithelial cells, mesangial cells, endothelial cells, and epithelial cells of Bowman's capsule. The glomerulus filtrates blood to produce a glomerular filtrate containing substantially the same components as plasma components of which molecular weight is 10,000 or less. Generally, the filtration is controlled not to leak essential substances in blood, especially serum protein, to urine.

Glomerulus damage causes the growth of mesangial cells which are one of the glomerulus component cells and the expansion of a neighbor extracellular matrix to increase the amount of urinary protein excretion. It is known that the increase of urinary protein excretion further lowers the renal function by leading glomerulopathy to damage of renal tubules. Therefore, the inhibition of the urinary protein excretion is expected to improve various diseases associated with glomerulopathy. Such damage is derived from not only a primary disease but also a systemic disease such as diabetes. However, initiation and progression mechanisms remain uncertain and a fundamental method for treatment is not established.

As the present treating method, symptomatic therapies are carried out, but they have many problems. For example, the immunosuppressants are used for patients of nephritis because many types of nephritis are considered to be caused by immunologic mechanism, but nephrotoxicity occurs by the prolonged administration. Though steroids are also administered to the patients of nephritis, some nephritis are resistant to them. Recently, it is proved that angiotensin converting enzyme inhibitors (antihypertensive agents) are useful for nephritis. However, the medicament for nephritis without a hypotensive effect is required.

Accordingly, pharmacotherapy of glomerulopathy has been in a trial and error stage. The treatment of glomerulopathy is made more difficult by the fact that the cause of glomerulopathy is not all alike and clinical course full of variety can not easily be prospected.

As a treating agent for nephritis other than the above mentioned medicament, compounds described in JP-A-9-87176 are exemplified.

Compounds similar to those of the present invention are described in WO97/27174, EP0757984 A1, EP0757037 A2, WO97/45402, WO97/44315, WO96/00214, WO95/35276, and WO97/05865.

DISCLOSURE OF INVENTION

In the above situation, the inventors of the present invention have studied on the medicament which can inhibit the initiation and progression of glomerulopathy such as glomerulonephritis and diabetic nephropathy or decrease urinary protein excretion.

The inventors of the present invention made glomerulopathy model rats which leak urine proteins by using a nephritogenic antibody and searched for compounds inhibiting the initiation and progression of the damage of model rats. In result, the inventors of the present invention found that some sulfonamide derivatives inhibited the initiation and progression of glomerulopathy, especially glomerulonephritis and diabetic nephropathy through the inhibition of protein excretion and they are useful treating or preventing them.

BEST MODE FOR CARRYING OUT THE INVENTION

The effect as a treating or preventing agent is tested below.

(Animals)

Five to eight weeks old male Slc-Wistar rats were used in the experiment.

(Procedure for the Establishment of Nephritogenic Antibody)

Mouse monoclonal antibodies are established against rat glomeruli and the monoclonal antibodies which induced nephritis are screened as described below.

To induce glomerulonephritis by the injection of antibody, the presence of the antigen on the cell surface is required. First of all, we investigated by immunofluorescence whether or not obtained monoclonal antibodies accumulate in the glomeruli after the intravenous injection to rats. The antigen recognized each clone of monoclonal antibodies was defined its distribution and molecular weight. Furthermore, nephritis-inducing activity was evaluated based on the urinary excretion of protein within a week after single injection of antibody.

During this study, a monoclonal antibody E30 was established (J.J.N., vol. 36, p106, 1994). It has been known that E30 recognizes the surface antigen of mesangial cells by the immunohistochemical study, and that single administration of E30 to rats induces complement-dependent mesangial cell injury. The pathological changes are described below.

E30 antibodies immediately bind to the surface antigens of mesangial cells in glomeruli after a intravenous injection to rats, followed by the activation of compliment system within 30 min. And then, degeneration and necrosis of mesangial cells are occurred, resulting in the detachment of glomerular basement membrane from mesangial area. A series of these pathological features is known as mesangiolysis. Accumulation of platelet and infiltration of inflammatory cells such as polymorphonuclear leukocyte and macrophage are observed during mesangiolysis. Mesangiolysis is prominent 1-3 days after the injection of the antibody and mesangial expansion is frequently observed at that time. Proliferation of glomerular cells, mainly mesangial cells, is initiated 3-5 days after the injection, resulting in the morphological features of mesangial proliferative glomerulonephritis by a week. The reconstruction of the glomerular capillary network is accompanied with mitosis and proliferation of mesangial cells and irregular patterns of angiogenesis. After then, increased number of mesangial cells and overproduced extracellular matrix are resolved with time course and the pathological features recover to the normal one by a month.

Thus, since a single injection of the monoclonal antibody induces a reproducible nephritis model, the antibody-induced nephritis model is useful for grasping a basic changes in glomerular disease as a biological response.

In Asia, a half of the patients with glomerulonephritis was diagnosed as IgA nephropathy. IgA nephropathy is characterized as IgA deposition to glomerular mesangial cells. IgA nephropathy belongs to proliferative nephritis caused by immunoreaction against mesangial cell itself Therefore, the monoclonal antibody-induced nephritis model is also useful for studying the pathogenesis of IgA nephropathy.

In addition, the monoclonal antibody, E30, is available for establishing some chronic nephritis models induced by the combination dosing with puromycin aminonucleoside (J.J.N., vol. 39, p220, 1997) or by a single injection of it to uni-nephrectomized rats (J.J.N., vol. 39, p300, 1997). The preventing or treating effects of test compounds on the development of glomerulosclerosis could be evaluated by utilizing these chronic nephritis models. Similar experiments can be examined by using following methods: 1) methods by using other monoclonal antibodies or anti-thymocyte serum instead of E30, 2) methods by using hereditary nephrosis rats or mice, 3) methods by using spontaneously diabetic rats or mice, and 4) methods by using streptozotocin- or alloxan-induced diabetic rats or mice.

(Protocol for Assay)

In order to induce glomerulonephritis, E30 of 20 to 500 μg, preferably 50 to 200 μg, is intravenously injected to rats of five to eight weeks old. Test compounds of 0.1 to 500 mg, preferably 1 to 200 mg, are suspended with 3 to 10%, preferably 4 to 6%, gum arabic solution and the like, and are orally given 1 to 5 hours, preferably 1.5 to 3 hours, prior to E30 injection. Constant amount of test compounds are then consecutively given 1 to 3 times a day. Evaluation of test compounds are determined by the amount of urinary protein excretion 2 days after E30 injection when proteinuria reaches to the maximum level.

As for some compounds which exhibit antiproteinuric effects in the method described above, the amount of urinary protein excretion during 5 to 8 days, changes in body weight, morphological changes in glomeruli by autopsy, inhibitory ratio of mesangial proliferation and renal function are assessed after the treatment of these compounds.

Determination of the amount of urinary protein excretion is performed by the collection of 24-hour urine samples with stainless metabolic cages followed by the measurement of the concentration of urinary protein. Blood samples obtained at the follow-up period are processed for the determination of blood urea nitrogen and plasma creatinine, which indicate renal function. As a marker of damaged renal tubules, urinary amounts of N-acetyl-D-glycosaminidase excretion is measured. Furthermore, to study the inhibitory effects of compounds on mesangial proliferation following E30 injection, the number of PCNA (proliferating cell nuclear antigen) positive cells per single glomerulus is counted. Morphological changes are observed with light and electron microscopy.

The present compound represented by the formula (I) which useful as the composition for treating or preventing glomerulopathy is may be synthesized in accordance with the method described in WO97/27174.

The term “compound of the present invention” herein used includes pharmaceutically acceptable salt or hydrate of the compound. The salt is exemplified by a salt with alkali metals (e.g., lithium, sodium, potassium, and the like), alkaline earth metals (e.g., magnesium, calcium, and the like), ammonium, organic bases, amino acids, mineral acids (e.g., hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and the like), or organic acids (e.g., acetic acid, citric acid, mallein acid, fumaric acid, benzenesulfonic acid, p-toluenesulfonic acid, and the like). These salts can be formed by the usual method.

When the compound of the present invention is administered to a person for the treatment or prevention of the above diseases, they can be administered orally as powder, granules, tablets, capsules, pilulae, and liquid medicines, or parenterally as injections, suppositories, percutaneous formulations, insufflation, or the like.

TEST EXAMPLE TEST EXAMPLE 1

5-week-old male Slc-Wistar rats were reared under the conditions of room temperature of 25° C., 40-60% humidity and 12 hour cycles of light and darkness and fed on solid chow (CA-1, Clea Japan) and tap water ad libitum. After one week's preliminary rearing, each rat was housed in a stainless metabolic cage for acclimation for one week, and was used for experiment at 7 weeks of old (body weight: 150-180 g). E30 monoclonal antibody (J.J.N., vol. 36, p106, 1994) was diluted with saline at 100 μg/0.4 ml and was administered from tail vein at the volume of 0.4 ml/body. Compound (2) was suspended with 5% gum arabic solution and was given at the dose of 100 mg 2 hours before E30 injection. Subsequently, compound (2) of 100 mg was orally administered once a day from the next day. The rats were housed in stainless metabolic cages just after the administration of test compound, and then 24-hour urine samples were collected. After measuring the volume, the urine was centrifuged at 3000 rpm for 10 min at room temperature. The supernatant was used for the determination of urinary excretion of protein. Urinary protein was determined by pyrogallole red method (Micro TP-test Wako, Wako Zyunyaku). The amount of urinary protein excretion on day 2 in compound-treated group was compared with that in vehicle-treated one, and inhibitory ratio of urinary protein excretion was calculated. The results are shown in Table 11. The compounds (1) and (3) to (121) were examined in a manner similar to that described in the above method and the results are shown in Table 12. FIG. 1 shows the change in urinary excretion of protein throughout the experiment.

On the follow-up day (day 5), animals were subjected to ventrotomy under anesthesia with pentobarbital, and then, kidneys were removed immediate after blood collection, fixed in 10% formalin or methacarn solution. The tissue samples fixed with formalin were embedded in paraffin. Sections were stained with the periodic acid-Schiff reaction and processed for light microscopy. On the other hand, the paraffin sections of tissue samples fixed with methacarn solution were processed for immunohistochemistry with anti-PCNA antibody (mouse anti-PCNA IgG). After then, the number of PCNA positive glomerular cells belonging to S phase within the cell cycle were counted. The result is shown in FIG. 2.

On the follow-up day (day 5), blood samples were collected and processed for the determination of blood urea nitrogen and plasma creatinine. Concentration of blood urea nitrogen was measured with Creatinine-test Wako (Wako Zyunyaku). The result is shown in FIG. 3. Concentration of plasma creatinine was determined with Urea nitrogen B-test Wako (Wako Zyunyaku). The result is shown in FIG. 4.

TEST EXAMPLE 2

Mesangial cells isolated from glomeruli of male Wistar rats aged 4 weeks old were plated on wells of a 96-well tissue culture plate at a density of 1000 cells per well and cultibated in RPMI medium containing 20% fetal calf serum for 24 hours. Following incubation for 20 or 44 hours, ³H-thymidine (100000 dpm/well) was added in the cell-culture medium. Four hours later, cultured mesangial cells were washed followed by cell lysis with 0.1% SDS and deoxycholate (0.1 mg/ml). Measurement of incorporation of ³H-thymidine was determined by counting radio activity with liquid scintillation counter, and the ratio of incorporation was calculated. The result is shown in FIG. 5.

From the results summarized in FIG. 1 and Table 12, it has been proved that the amount of urinary protein excretion in test compound-treated group decrease significantly. It is known that the increase of urinary protein excretion is well associated with damaged glomeruli (as same as in human), therefore, proteinuria is a good indicator of renal dysfunction. After the injection of E30, the amount of the urinary protein excretion remarkably increased. Renal function in rats with E30 monoclonal antibody became detrimental. In test compound-treated group, urinary protein excretion was significantly suppressed, indicating that the compound served as a preventing or treating agent against glomerular injury.

As shown in FIG. 2, cell proliferation was suppressed in test compound-treated group. Extraordinary proliferation of mesangial cells are observed in glomeruli 5 days after a injection of monoclonal antibody (observation with light and electron microscopy). The proliferating cells could be detected by immunohistochemistry with PCNA antigen expressing during S phase within the cell cycle. Therefore, comparison study of the number of PCNA positive cells per single glomerulus between vehicle-treated group and test compound-treated one provided the evidence as described above.

FIG. 3 shows that concentration of blood urea nitrogen in test compound-treated group decreased significantly. Therefore, decrease in renal function (glomerular filtration rate) was modified by the treatment of test compound, indicating that the compound served as a preventing or treating agent against glomerular injury.

FIG. 4 shows that concentration of plasma creatinine in test compound-treated group decreased significantly. Therefore, decrease in renal function (glomerular filtration rate) was modified by the treatment of test compound, indicating that the compound served as a preventing or treating agent against glomerular injury.

FIG. 5 shows that the test compound inhibited serum-induced mesangial proliferation in a dose-dependent manner. This experiment was designed to define whether the inhibitory effect of the test compound on mesangial proliferation, as shown in FIG. 2, was originated from its direct effect (on the cells) or not.

As shown in the above results, it is clearly recognized that the compounds of the present invention suppress the amount of urinary protein excretion and the proliferation of mesangial cells mostly observed in glomerulopathy. The state of a disease occurred in these experimental models is similar to the human glomerulonephritis and diabetic nephropathy. Therefore, the compounds of the present invention are useful for a composition for preventing or treating glomerulonephritis and diabetic nephropathy.

Assay for Inhibitory Activities of MMP-9 and MMP-2

The enzymatic activity was analyzed on the method described by Knight, C. G., et al. (C. Graham Knight., Frances Willenbrock and Gillian Murphy: A novel coumarin-labelled peptide for sensitive continuous assays of the matrix metalloproteinases. FEBS Lett., 296 (1992) 263-266).

MMP-9 was purified by using a combination of procedures described in previous reports as follows.

J. 278 (1991) 179-187.

Briefly, human fibrosarcoma ATCC HT1080 cell line was cultured to confluent in Dulbecco's Modified Medium (DMEM) containing 10% fetal-calf serum at 37° C. for 48 hours. Subsequently, the medium of confluent culture was changed to serum-free DMEM medium. To obtain MMP-9, Phorbol-12-myristate-13-acetate (TPA) must be added to this serum-free DMEM medium at a concentration of 50 ng/ml. The TPA treated medium was centrifuged at 3000 rpm for 15 min and the supernatant was concentrated to 450 ml by a Toyo-Roshi UP-20 apparatus with an ultrafiltration membrane. Then, proMMP-9 in this concentrated solution was purified by using columns of Gelatin-Sepharose and Concanavalin A-Sepharose. The pool containing proMMP-9 was dialyzed, concentrated (Toyo-Roshi UP-20) and applied to columns of Sephacryl S-200 and Green A matrix for the separation from TIMPs. The obtained proMMP-9 fraction was activated by TPCK-Trypsin (final conc. 3 μg/μl reaction mix.) for the assay.

MMP-2 was purchased from Yagai (Yamagata pref., Japan).

MOCAc-Pro-Leu-Gly-Leu-A2pr(Dnp)-Ala-Arg-NH₂ as a substrate was purchased from Petide Institute(Osaka pref., Japan). This substrate was dissolved in DMSO at a concentration of 1 mM.

After standing for 60 minutes at room temperature, the reaction was started by adding 1.0 μl of a substrate solution. After incubation for 60 minutes at room temperature, 100 μl of 3% (v/v) AcOH for reaction stopping and measured a fluorescence with excitation and emission at 320 nm and 405 nm, respectively (Spectrophotofluorometer; Fluoroscan Ascent (Labsystem)).

The measurement of the inhibitory activities (IC₅₀) was carried out in a following four methods;

A) Reaction with substrate, enzyme and inhibitor

B) Reaction with substrate and inhibitor, without enzyme

C) Reaction with substrate and enzyme, without inhibitor

D) Reaction with substrate only

IC₅₀ values were calculated by using a following formula and each fluorescence values of above four methods (A to D).
